FAQ: PayPal IPN for Joomla

Q1: The transaction states: “Wrong transaction” “Someone attempted a sale using a manipulated URL” under Logs.

I have successfully installed 1 product, with the button code on the form, which redirects to PayPal and allows me to complete payment. I set the product to be “Download link in Email”.

However, I never received an email, and under Logs, the transaction states: “Wrong transaction” “Someone attempted a sale using a manipulated URL”.

Answer: This problem is always caused by a mistake configuration in PayPal IPN options, from email section. Please check there is no space in the end of your email.

When adding products within the component, the price field has USD currency symbol beside this, without any options to change the currency. I will be selling in EUR – how can I change the default currency?

Answer: You can sell your product in EUR, but the user interface is not ready for you to set the currency manually. You can follow these steps to change the currency as Euro:

After uploading a zip-File we get the error message: "Error: Uploaded file size is bigger than 20M!" - is there a possibility to change the allowed upload size?

Answer: If you want to upload big files, we suggest you to upload them by ftp software, because it is unstable to upload very big file by HTTP upload. I am using "FileZilla" to upload big zip files to my server. You can follow these steps to do it:

Creat a sample text file and rename it as same as the file you want to upload. For example, myvideo.zip

Add your digital product with this fake product file

Open your ftp software and find out your extension Joomla administrator folder, the folder location will be /www/yourJoomlaSite.com/administrator/components/com_pinp/pp_dg_upload/

Upload and replace the face file with your real zip file
